How does Gpwd Center compare with other water systems in Will County?

By EPA's size categories, Gpwd Center is a very small system (500 people or fewer). Will County has 236 active public water systems. Its population served is well below the county average of 2,607 people per system, and accounts for less than 0.1% of the 615,219 people reported by systems filed under the county. Across Illinois, the 3,872 active systems average 3,204 people each. Nationally, the average active non-transient non-community water system reports serving 430 people, so Gpwd Center is well below that figure.

What does “non-transient non-community water system” mean?

A non-transient non-community water system regularly serves at least 25 of the same people for more than six months a year, but not where they live. Schools, factories, office buildings and hospitals with their own supply are typical examples. Illinois has 396 active non-transient non-community water systems, 10% of the state's 3,872 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 2,808 Illinois systems (73%) list groundwater as their primary source.

Who owns and regulates Gpwd Center?

EPA lists Gpwd Center as privately owned. The IL state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 162 of the 236 active systems in Will County (69%) are also privately owned.

Does Gpwd Center have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in January 2026. The violations listed here began between October 2017 and January 2026. By type: 8 monitoring and reporting, 1 public notice, recordkeeping or other, 1 required treatment not met, 1 monitoring and 1 reporting. The contaminant or rule involved most often is Revised Total Coliform Rule (3 of them). EPA lists 10 as resolved and 2 as archived. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status.
